HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 228,504, dated June 8,1880.

Application filed April 27, 1880.

To all whom ti may concern:

Be it known that I, WILLIAM A. WRIGHT, a citizen of the United States,residing at (Jentreton, county of Burlington, and State of New Jersey,have invented a new and useful Ii'nprovementin Horse-Powers, whichimprovement is fully set forth in the following specication andaccompanyingdrawings, in which- Figure l is a top or plan view of thehorsepower embodying my invention. Fig. 2 is a side elevation thereof.Fig. 3 is a vertical section thereof in line a m, Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

r 5 My invention consists of a horse-powcrhavin g means for releasingthe winding-drum and preventing the reversal ofthe same, the parts beingcombined and operating as hereinafter fully set forth.

Referring to the drawings, A represents a frame, to the top and bottomcross-pieces, a b, of which is mounted a vertical shaft, B. 0 representsa tongue, which is connected to the upper end of the shaft B above thecross- 2 5 piece a, and to which the animal is hitched, and dependingfrom the said tongue near its connection with the shaft B is a hingedpawl, D, which is adapted to engage with the teeth of a circular rack orratchet, E, secured to the 0 top cross-piece, a, the shaft B passingfreely through a central opening of said rack or ratchet E.

On the lower end of the shaft B is loosely fitted a winding-drum, F, andabove the same is a clutch, G, which has both a rotary and verticalsliding connection with and on the said shaft B, and is adapted toengage with lugs on the drum F.

(No model.)

In order to raise or disengage the clutch G from the drum F, I mayemploy a lever, H, whose inner end is bifurcated and provided with pins,which project freely into a horizon tal groove in the clutch.

It will be seen that when the drum is to be rotated in order to wind therope or chain thereon the clutch G is lowered, and as the animal carriesaround the tongue 0 power is communicated to the shaft B and clutch G,and thus to the drum.

When it is desired to release the drum to o stop the winding action orreturn the rope or chain, the lever B is operated in order to raise theclutch G, and thus the drum F is free or again loose on the shaft B.

During the rotation of the shaft the pawl D rides freely over the rackor ratchet E; but should the animal attempt to back, or there is anunusual strain on the rope or chain, and thus on the drum F, when thelatter is operative, the pawl engages with one of the teeth of said rackor ratchet and acts as a stop to the rotation of the shaft and connectedparts, as is evident in referring to Fig. 2.

H avin gthus described in y invention, what I claim as new, and desireto secure by Letters Patent, is

The shaft B, tongue 0, pawl D, rack or ratchet E, drum F, and clutch G,combined and operating substantially as and for the purpose set forth.
